Abstract: The invention relates to a diffractive device for chemical and biological analysis based on structured receptors on waveguides, which comprises: a waveguide and a recognition element consisting of a grating with receptors arranged on the waveguide and are intended to interact with target compounds present in a sample; and a radiation source that emits an incident beam propagated through the waveguide, interacting with the recognition element and being diffracted according to Bragg's law, thereby generating a reflected beam and a transmitted beam, which are collected by optical analyzers that record parameters of the reflected beam and of the transmitted beam, enabling multiple analyses to be conducted in a simple, fast, 15 sensitive and quantitative manner, label-free and in real time.

Abstract: The disclosed broadband supercontinuum light emitting device includes a nonlinear optical fiber, a pump system, a cavity, and an active medium. The active medium may comprise an active fiber and may be located inside the cavity. The active medium is configured and arranged, by means of a pumping provided by the pump system, to generate and emit chaotic pulses of laser light towards the nonlinear optical fiber, which excite the nonlinear effects thereof for the generation and emission of supercontinuum light in the form of pulses of light distributed randomly over time. Numerous uses of the device are disclosed for multiple applications that require a low-cost, very bright light source with an adequate broadband spectrum.
